I was surprised to learn Taiwan has dabbled in nuclear weapons in the past. They actually got caught developing them and had to swear they'd stop.
Given that the US is doing a professional wrestling 'heel turn' and is now The Bad Guys, I wouldn't be surprised if, like NK, they just come out and announce that they have nukes. Honestly, and this is bad for the world but smart in a game theory sense, I think a lot of countries that depended on the US being a force for stability either go the Israel route ("We won't say if we have nukes or not" wink) or just announce that they have them and do public tests to prove it.
